The programmer works fine, I use it to program eeprom memories.
Suggestions that could be added to the programmer:

That complicates the code a little bit but I suppose it could be done.
Thanks for the suggestion.
Memories 25cxxx and 95cxxx can not be programmed if the status register is protected.
First you have to remove the protection.
In electronic equipment these memories are protected
como quitar la protección en estos dispositivos
This is already done before writing.
The suggestion is for selecting the desired block protection afterwards.

The 25020 can not be recorded if protected
Please provide a write log and device details.
Hello,
I am trying to programm a 25VF010 (25X10 with low voltage ext.board) eeprom chip pulled out of a working hdd board, but writing gives errors. Reading seems to be working as I get always one and the same checksum. When writing is started,the program gives message that chip has been erased OK, and later, writing returns errors. Reading after writing returns the same checksum, means that erasing and writing are not working.
Please advice how to write this type of eeprom (25XXX)? Attached is a log message.
From a very cursory look at the datasheet, it seems that the 25VF010 requires an additional instruction prior to erase. You should compare the two datasheet in detail and find all the differences. If this is the problem it should be easy to add the missing instruction to opgui.
hola un saludo, me secede lo mismo con las 25 que he probado
hola un saludo. armé el grabador y también me hace lo mismo con las SPI las lee pero no las graba.
Hello, I couldn't record the SPI memories used, please write error. I had to erase them first with an Arduino so they would record without a problem. I'd like to suggest an individual delete button like this one for read and write. so you can only erase the chip if desired. sorry for any translation problem I speak Spanish.
Which SPI memory?
Hello, greetings again, the SPI Memory that does not record is 25L3206, 25L4005 after deleting it they are recorded correctly. Greetings.
